refactor(api): replace AutoRenewRedisLock with DbMigrationAutoRenewLock

- Updated the database migration locking mechanism to use DbMigrationAutoRenewLock for improved clarity and functionality.
- Removed the AutoRenewRedisLock implementation and its associated tests.
- Adjusted integration and unit tests to reflect the new locking class and its usage in the upgrade_db command.

(cherry picked from commit c812ad9ff26bed3eb59862bd7a5179b7ee83f11f)
